UNITED STATES PATENT OFFICE HENRY B. OHIEB AND WILLIAM ILL CARROLL, OI DAYTON, OHIO, ASSIGNOBS 'I'O OHIEB FARE REGISTER COMPANY, 01' DAYTON, OHIO RECORDING DEVICE Application. filed June 27, 1927. Serial No. 201,789.

This invention relates to improvements in recording devices, and, in particular, is designed to record the elapsed time that the instrument was in use.

6 For instance, an airplane may be hired for which a certain charge will be made based on the number of hours or fractional parts thereof that the airplane is used. Sometimes automobiles are employed on the same basis,

10 as well as other machines.

The present recording device is designed so as to show whether or not it is recording and is provided with a clock mechanism to show the correct time. The face of the clock 15 is conventional. The machine is also provided with a series of drums to show the number of hours and fractional parts thereof that the indicating device has been in recording position. Means are also provided to cause the recording mechanism to become operative when a lever, corresponding somewhat to the flag of a taximeter, is in either of two positions. Sometimes an airplane or automobile are operated either from the magneto or the battery according to the position to which a switch is turned. The said switch controls the position of the said lever so that the machine is rendered operative so as to record regardless of whether the airplane or automobile are being operated from either the magneto or battery.

A further object of the invention relates I to a novel resetting means for the clock hands which may be reset to correct position without interfering with the registering drums. Anotherobject of the invention relates to an improved clutch device.

Other objects of the invention will appear in the detailed description of the invention.

In the drawings, .Fig. 1 is a front elevational view with the lower part of the face plate broken away. Fig. 2 is a cross-sectional view approximately on the line 2-2 of Fig. 1. looking in the direction of the arrows.

Fig. 3 is an elevational view approximately on the line 33 of Fig. 2, looking in the direction of the arrows.

Fig. 4 is a plan view partly in cross section, approximately on the line 4--4 of Fig. 2.

Fig. 5 is a cross-sectional view a proximately on the line 5-5 of Fig. 2; an

Fig. 6 is a detailed view of the lever mechanism to actuate the sign to indicate whether or not the machine is recording.

Referring more particularly to the drawings, a rectangular casing 1 is provided having a face plate 2, the casing 1 being provided with securing lugs 3. The upper portion of the face plate 2 is provided with asight opening 4 behind which is a plate 5 on which is written the word Recordin or other suitable wording. A clock dia6 is placed behind the mid portion of the face plate 2 on which dial appears the conventional features of a clock face. Near the lower portion of the face plate 2 is a sight opening 7, through which Ina be read the drums having thereon the sum of elapsed time.

Within the casing 1, a clock frame 8 is provided which is secured to the casin 1. Below the clock frame 8 is a frame 9 which frame carries the majority of the shafts of the mechanism. Within the clock frame 8 is a conventional clock mechanism, not shown, which drives a gear 10, which meshes with a pinion 11 which is fast on a hollow drum 12. The pinion 11 and drum 12 are loosely mounted on the shaft 13. The pinion 11 is provided with a hollow chamber 14 which receives a spring 15 which presses against a collar 16 fast on the shaft 13. The shaft 13 has rigidly attached thereto a unit consisting of a leather friction member 17 a metal disk 18, collar 19, gear 20, setting gear 21, flange 22 and collar 23.

A setting key 24 is received in an opening 25 in the casing 1, and its inner end is received by a collar 26 fast on a shaft 27, which carries a setting gear 28 rigidly secured thereto. A spring 29 is interposed between the collar 26 and a shoulder 30 of the casingsl'o that normally the gear 28 will be out of mesh with the gear 21, but when the operator presses inwardly on the key 24, the spring 29 is compressed and the shaft 27 and gear 28 are moved so that the gear 28 is brought into mesh with the gear 21. The operator may now rotate the key 24 and thereby rotate the gear 21 together with the members secured thereto. This rotation, however, would not be imparted to the drum 12, pinion 11 or gear 10, for the clock mechanism would prevent 'such a rotation and the leather friction member 17 would rotate relative to the drum 12. The gear 20 meshes with a gear 31 slidably mounted on a shaft 50. The gear 31 has rigidly secured thereto a collar 32 and a gear 33, which gear 33 meshes with and drives a pinion 34'on a shaft 35,'which pinion 34 meshes with and' drives a gear 36 rigidly secured to a shaft 37, which shaft carries a worm 38 which meshes with and drives a pinion 39 secured to a shaft 40 on WlllCh is rigidly clock. A gear 42 meshes with the pinion 39, which gear 42 is connected to a disk 43 by means of a shaft 44. The disk 43 is provided with two pins 45 which drive a gear 46 connected to the hour hand 47 of the clock mechanism through a sleeve 48 surrounding the shaft 40. It is, therefore, obvious that the clock hands may be reset by the key 24 without in any wise disturbing the mechanism within the frame 8.

A signal is provided to show whether or not the machine is recording as hereinafter described. The signal mechanism is controlled by a lever 49 pivoted to the frame work by a pin 51, which lever 49 is provided with two cam lobes 52 and 53 forming a modified cycloidal curve. A lever 54 is pivoted on a pin 55 which lever carries a stud 56 on which is mounted a roller 57. The lever 49 is operatively connected with a switch not shown, which switch may be any two-way switch such as one which operates either from the .magneto or the battery. When the lever 49 is positioned by the switch so that the machine is being operated from the battery, one of the lobes, such as the lobe 53, will be moved so as to raise the roller 57 and lever 54. A like movement would occur when the lever 49 is moved in the opposite direction, that is, when the switch is positioned so that the machine is operated from the magneto. Regardless, therefore, of what operative position the switch may be in, the lever 54 is raised and when the switch is cut off, the lever will be lowered by means of a spring 58.

The lever 54 is provided with a cutaway portion 59 which receives a pin 60 projecting from an car 61 carried by a lever 90 pivoted on a pin 91. The lever 90 is provided with aperture 92 which receives a pin 93 carried by a slide rod 62. The upper end of the rod 62 is provided with a projection 65 having a recess 66, which recess receives one end of a lever 67 pivoted on a pin 68. The other end of the lever 67 in operatively connected with a sign 69 on which appears the word Not or other suitable insignia. When the lever 49 is in the position shown in Fig. 3; that is, in neutral position, the lever 54 will be depressed so that the word Not will apmounted the minute hand 41 of the pear in conjunction with the word Recording and the entire sign would read Not recording. When the lever 49 is moved into either of its operative positions, the word Not would be lowered so that the only word which would appear would be Recording. Obviously, signs having other wording could be employed so long as the signs serve to indicate the operative condition ofthe regis-' ter.

A bell crank lever 70 is ivoted on a projection 71 carried by the ame work of the register, which lever is connected with the lever 54 by means of a link 72. The bellcrank lever 70 carries a pin 73 to which is connected a rod 74, which rod has arms 75 (Fig. 2) forming substantially a semi-circle, which arms rest in a channel 76 in a collar 77 securely attached to the gear 31. As before mentioned, this gear 31 is driven by the clock mechanism and is connected to the gear 33 by means of a collar 32. The ear 33 has secured thereto a clutch member 8. The collar 77, gears 31 and 33, collar 32 and clutch member 78 will be shifted to the right when viewed in Fig. 5 whenever the lever 49 is moved into either of its operative positions so as to raise the lever 54, link 72, bell crank lever 70 and rod 7 4, thereby engaging the clutch member 78 with the corresponding clutch member 79 secured to a gear 80. The clutch member 79 and gear 80 are slidably mounted on the shaft 7 50 and are yieldably pressed toward the left when viewed in Fig. 5 by means of a spring 81; When the clutch member 78 is moved into contact with the clutch member 79, the spring 81 allows the clutch member 79 to move slightly so that the two clutch members are yieldingly pressed to ether. The gear 80 is a Geneva gear provide with five long teeth 82, which gear 80 drives a Geneva gear 83 two teeth each time the gear 80 makes, onefifth of a revolution. The gear 83 meshes with and drives a pinion 84 on a shaft 85'connected to a registering drum 86, which registers fractional portions of an'hour. The drum 86 is operatively connected by means of any suitable transfer mechanism with other indicating drums, such as a drum 87 to designate thenumber of hours, less than ten, the drum 88 to indicate the tens of hours v hands were turned backward, the drums 86,

87, 88, etc. would'not thereby be reversely rotated for the clutch members 78 and 7 9 are so designed that they will overrun on such reverse movement. In other words, these members form a one-way clutch.

When the switch is thrown into either of its operative positions, the lever 49 would be correspondingly moved so as to lower the sign carrying the word Not and the clutch members 7 8 and 79 would be brought together so that the clock mechanism would thereafter drive the indicating drums through the gearing connecting the clock and the gear 33 and from thence through the clutch members 78 and 79, Geneva gears 82 and 83 and pinion 84. It is fully realized that other mechanism might be employed to accomplish the same results and it is, thereiore, desired to cover this invention in whatever form it may be embodied which may fairly fall within the terms of the appended claims.

Having now described the invention, we claim:

1. In a recorder, a clock, indicating drums, a lever, a shaft, a gear mounted on said shaft, means operatively connecting said gear and lever whereby said gear is shifted longitudinally of said shaft by said lever, a clutch member operatively connected to said gear, a second clutch member operatively connected with said indicating drums, said clutch members being engaged when said lever is in either of two positions and disengaged when said lever is in a third position, and means operatively connecting said clock and gear. 2. In a recorder, a clock, a shaft, a pinion and a drum carried by said shaft, means operatively connecting said clock and pinion, a gear secured to said shaft, a friction clutch interposed between said gear and drum, a second gear secured to said first mentioned gear, resetting means, means whereby said resetting means may be operatively connected to or disconnected from'said second gear, means whereby said first mentioned gear is operatively connected to the clock hands, indicating drums, and means whereby said first mentioned gear may be operatively connectfld to or disconnected from said indicating runs.

In testimony whereof we aflix our signatures.
